I'm considering a move to LED lighting. I've been reading some good reviews on the Sunbrite LED Lighting Fixture with their Gen2 LED tubes. Apparently their first generation LED tubes had some design flaws and were not very good. I spoke to my LFS (Vivid Aquariums) who recently started carrying the product line, and they speak highly of them. They have them in use on three different aquariums of different coral stocking. I'm interested in how the individual LED Tube control timers function. I couldn't find any information except that individual control of each of the eight Tubes is provided and you could produce a sunrise/sunset effect. I'm planning a trip to Vivid Aquariums, but would like to have some questions to ask. Does anyone have any first had experience with them? Would like any information you have. Thanks!!
